1.5. Generating Programming Files for Partial Reconfiguration

The following sections describe generation of bitstream and other files for partial reconfiguration.
Note: You must assign all I/Os in your design before you can generate a .sof file for programming the target device. Starting in Quartus® Prime Pro Edition version 25.1.1, the Assembler does not generate a .sof programming file during compilation unless all I/Os have location and I/O standard assignments. Previously, Quartus® Prime Pro Edition only issued a critical warning during the Fitter stage if a design lacks complete pin location and I/O standard assignments but still allowed .sof generation.
